LIME COLOR.

subject of the King of Saxon and residing at Radebeul, near Dresden, (Jermany, have invented certain new and useful Improvements in Lime Color, of which the following is a specification.

The object of the present invention is to produce a lime color which is fast and able to withstand the weather like oilcolor; and this object is reached by the following mixture: One hundred and eighty grains crude nitric acid of 32 Baum, or crude sulfuric acid of 42.6 per cent,, or eighty grains ninety-sixper cent. sulfuric acid (6566 Baum) are poured into two hundred and fifty grains hu-' man feces, as urine, and the human excre ments mixed up together as it is by nature, containing solid matter, and filtered while stirring, and to the filtrate seventy grains crud-e glycerin are added. One hundred grains of this acid liquid are mixed with about. one hundred and twenty grains of caustic lime (a good white lime which has been powdered and sifted) and stirred to a thick pap and finally ground with an ordinary color-mill. The so-obtained thick lime pap is then, each time it is used, thinned with water till convenient forpainting, and for about one hundred grains color-pap 30-35 grains of water are necessary. By the presence'of the lime in the mixture of nitric and sulfuric acids, filtered manure, and g1 cerin calcium nitrate or calcium sulfate is ormed,

which with the sulfates of the manure form calcium sulfate, (gypsum,) and also the albuminous' particles of the manure combine with lime. By this means a hard mass is formed. The addition of glycerin gives the color the necessary fluidity and prevents premature drying. toned down as wishedwith lime pure bri ht colors and can be applied as any other co or, with a brush on whitewash, stone, cement, wood, &c. It hardens more and more in the air and is very durable. instead of oil color for out and in side coats, in which case. each coating does away with possible molding, peeling, and sto 'pa e of the necessary air c1rculation-the isa vantages of oil color.

What I claim is- The method of preparing a fastlime color consisting in adding acid to,two hundred and fifty grains of human feces, as urine and human eXcrement mixed up together as it is by nature and containing solid matter, filtering, While stirring, adding to the filtrate seventy grains of crude glycerinand to each one hundred grains of this acid liquid adding one hundred and twenty grains of lime.-

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses,
